#Ultrasonic #record cleaners are GAME CHANGERS. My $5 used vinyls sound nearly MINT! Holy cow. #vinyl #VinylRecords

Wondering what is happening, but dsub and ultrasonic go silent after playing a song. So you play a song, and the one it plays after will play, but quiet. Until I press pause/play or rewind. Both in online en offline mode, tried resetting the cache...

One exploit I love to demo: nUHF / #ultrasonic tracking. Digital mics can pick up sound not audible to humans embedded in ads, apps, or even lightbulbs (yes, really). You couldn't hear it, but your machine did.
"Breaking news: #ultrasonic mumbo jumbo claims to cut friction by 20%! But wait, before you get too excited, the article has vanished into the void of a 400 error.
Perhaps the real #innovation here is in how to make content disappear faster than a magician's rabbit."

Anyone in Toronto want some #ultrasonic cleaners? First picture is from the old Amazon listing in 2023 (not present now).
I have a 6L and a 10L model. Not used all that much. The heater packs on them are absolute garbage (better to boil water yourself and then add it for PCB cleaning), but the sonic function works just fine.
I think I have some fluid too, which I'll throw in if you have both units.
I'd like $100 for the pair, but am open to offers. Collection only.

I know the general rule in life is you get what you pay for, but does anybody have any experience with this cleaner? Seems too good to be true, over £300 cheaper than a HumminGuru. #vinyl #ultrasonic

Another one for the #maker, #3dprinting, and maybe #science bubble:
What, if any, are the considerations when selecting a reasonably priced decent quality #ultrasonic cleaning bath?
Use case would be to clean and degrease/deoil small tools, glasses, watches, etc. Maybe a second unit some day to experiment with e.g. wood-chip infused milk; that second unit would remain food-safe.
I didn't get much farther than "probably stainless steel, and correct volume" -- and select that from eBay?
